Well is not the expression, #A=epsilonbc#?

Explanation:

Where #A="absorbance"#, a dimensionless quantity......

And #epsilon="molar extinction coefficient"#

And #b="path length of cell"#

And #c="concentration........."#

Given that #b# and #c# have units of #cm#, and #mol*L^-1#, should not #epsilon# have units of #cm^-1*L*mol^-1#. And thus as concentration grows, absorbance should increase proportionally up to a point........
